"'UBRICATOR..

Specification of Letters Patent.`

Patented Aug. l5, 3.905.

Application filed October 25, 190.4. Serial No. 229,893.l

Be it known that I, HERMAN GAsLnii, a citizen oi' the United States, resid ing at Canastota, in the county of Madison and State of New York, have invented certain new and useful Improvements in Lul'n'icators, ot' which the following is a specilieation, reference being had to the drawings accompanying and forming part of the same.

My invention relates to devices for supplying oil to moving parts, and has for its object to provide a lubricating apparatus which will maintain a uniform supply of the lubricant. Various devices having the same purpose have been proposed; but so far as am aware these have generally included movable valves, pistons, or other moving parts. While such devices may operate with more or less success for a time` they lack the desired degree of durability. 'lhey deteriorate by refion of the wear of valves or other moving elements, and their operation is thereby impaired. 1 have theretore been led to devise my present invention, which eliminates ail moving parts in its normal operation. lt also makes provision for a considerable supply of oil, it' desired, so

'that the automatic operation of the device may go on for a practically indefinite period wtlioiit attention. It is obvious thata lubricator possessing suoli capabilities is adapted to very wide-application in the arts and, in fact, may be used with satisfactory results wherever a uniform supply oi" liquid lubricant is desired.

1n carrying out my inventionl employ a receptacle or reservoir which may contain the desired quantity ot' oil and deliver the hitter to the part or parts to be lubricated through a suitable conduit or tube. '.lhe fiow of oil through the conduit is governed by pneumatic 1' ressi`ire,.whieh in turn is crnitrolled by variation in the quantity ot' oil already delivered.

For suoli purpose l prefer to employ in connection with the feed-conduit an auxiliary reservoir or vessel wherein a constant level of oil may be maintained, so that the supply therefrom to the part or parts to be lubricated will be uniform.

In tlieaceonipanying drawings l have shown several forms ot' the invention, all applied to the crank-case oll an explosive-engine for the )uiposeof supplying oil to the crank ease or lliaiiiber, thereby constituting what is known is a `splashing-oder.

Figui-o l is a sectional view showing the preferred form. Fig. 2 isa sligiitly-modiied form, and Fig. 3 isa still further modilication.

Referring now more particularly to Fig. i, R indicates an air-tiglit reservoir oi' any coeveiiient size. Extending from the saine, prefv eral-)ly from the bottom, is an oil-conduit c, reaching into the auxiliary reservoir fr, of any suitable sizeand shape. In the embodiment illustrated thevlatter is provided with an airvent 1. The crank-ease ot' an explosive-engine is diagrainniatieally indicated :it C, and from the lower part ot' the same to the auxiiiary reservoir r extends a conduit or pipe c.

The operation ot' the above construction will now be readily understood. The reservoir r and conduit n are so arranged reiative to the crank-case U that the conduit terminates in the plane of the oil-level (indicated by the line l) which it is desired should be maintained in the crank-chamber. The airtight reservoir R being supplied with a snit-- able quantity ot' oil, air will enter throng-li the vent 'r and thence pass up the conduit r, permittingoil to iiow down into the in'teriiiediate reservoir 1'. When, however, the ed in the latter rises high enough to cover the orifice of the supply-pipe, the supply ot' air to the main reservoir will bc cut oi, and the air-pressure in the auxiliary chamber will prevent further downtlow of oil through the conduit c. In the meantime the crank-ease has also been supplied with oil up to the same level as in the intermediate reservoir. As the oil is consumed in the engine its leve?. falls until the oriiiceof the conduit c niicoveied to an extent sufficient to permit air to enter the same and pass up into the reservoir R, The partial vacuum therein being thus relieved, a small quantity ot' oil will tiow out, raising the level in the crank-case and intermediate chamber until the orifice of the supply-pipe is again covered, thus restoring the oil-level and cutting ofi the further admission of air, as before. lhis operation is tirely automatic and takes place whenever an additional quantity ot' oil is needed in the crank-case. for the proper operation oi the apparatus air-pressure iii the crank-ease and intermediate chamber must be the same, while that iii the supply-i'eseryoir is loss` by an amount equai to the weight oi' the column oi oil in the conduit n. The crank-case iii the present einbodimeiits must be in communicatioii with the atmosphere, and as merely indicative ot this lt will ot' course be noted that provided with a filling-aperture having; e

To insure en nir-tight joint ettliis point, e. gasket or seat of yieldingl Innterielsnch es leather, rubb'enleed, fc. may be interposed between the cap and the necir. This is fe milier construction end need not be further described herein.

The vrennovei of tine oeps vrooid of course relieve the partiel vacuum in the reservoir and permit any oil. therein to be discharged, raising the level the crenir-cese, or even escaping; through the vent in the interniediete reservoii. in order to nrevent sucia en occurm duit o with e veive, as p, end also provide de .vices forclosing the seme whenever the iii!- ing -enerture is uncovereda A simpie end convenient mechanism for this 'po'rpoee ie shown in it consists of e lever 1, fili crumed'on e standard and carrying" on one end the valve-plug im The ie-tter may be of hemisphericei form, ne shown, to on the discharge-orifice endfor the seme por pose may oe pivotell-j/ carried oy 'the iev r2 so es to hang always e Vertical position.

Upon replacing the cap the rod will be'depreesed,- raising the valve from its seat restoring the system to its operative condition it virili ot course be understood that the veiv meenemism just described is merely one o e if'eriety of devices which may be convenien tly used for the seine purpose.

The construction Shown in Fig. 2 is Similar to that ofP Fig. 1, except that the intermedin ate'rescrvoir r is located directif,7 on the crankcase. The necessity 'for e pipe to provide communication between the two tnerei'ore eliminated, that piirpose being served oy one or more passages c" through the Well of the crank-chamber.
